. YARN-TUBE UNIT.

Application filed October 10, 1928. Serial No. 667,630.

To all whom it may concern:

Be it known that I, CHARLES H. COLLINS, a citizen of the United States, residing at Amsterdam, in the county'of Montgomery and State of New York, have invented certain new and useful Improvements in Yarn-Tube Units, of which the following is a specification.

This invention relates to tube frames such as are used onAxminster looms, and the object of this invention is to improve the form, construction, and method of attaching the yarn tubes to the tube carrying angle of a modern tube bar. I

The tube frames used on Axminster looms com rise frame-carrying chain engaging mec anism mounted on the ends of a tube bar, which bar also has mounted thereon the usual tuft yarn spools and yarn tubes.

On some of the older types of Axminster looms which utilize tube frames for inserting the tuft yarns between the warp yarns, each individual yarn tube is fastened to the tube bar proper. In the more moderntypes of tube frames the individual yarn tubes are fastened to an angular stri of metal and the stri then fastened in p ace on the tube bar. This method permits of the handling of a lar e number of yarn tubes as a single unit an so expedites the attaching of the yarn tubes to the tube bar,'and is especially advantageous when attaching tubes to the latest types of tube bars which are of metal, or wood and metal.

My present invention lies in the method. of attaching the yarn tubes to, and in the constructionof, the angular strip of metal which is the tube carrying angle of a modern tube bar, and is clearly illustrated in the accompanying drawings, in which:

Fig. 1 is an end view of a section of my improved tube carrying angle with yarn tubes in place thereon, a portion of a tube piece.

frame, and D atuft yarn in place in a yarn;

bar and of a tuft yarn being indicated by dotted lines.

Fig. 2 is a front, and Fig. 3 is a rear view of a'portion of a tube carrying angle with a number of yarn tubes in place thereon.

The same reference characters refer to the same. parts throughout the several views.

Referring to the drawin s, A, A, represent yarn tubes, and B the tu carrying angle C indicates the tube'bar of a tu tube. A

My improved tube carrying angle B, is

edge of one made from sheet metal of suitable gauge, the free end 6 of the horizontal flange thereof being preferably turned back into itself so as to form a smooth edge and'at the same time assist in stiffening the angle as a whole. At the free end b of the vertical flange of the angle B, I make a'double bend, substantially as illustrated, so as to form a thickened edging 'or bead on the outside face of the flange. This edging is of additional importance as it not only strengthens the angle as a whole but rotects the tuft yarns by reventing their eing drawn into contact with the upper edge of the yarn tubes, and provides a convenient stop and gau e against which to ali the yarn tubes w en assembling tubes angle into a unit.

The vertical flange of the angle B is also provided with one or more rows of perforations 6 which perforations form an impor tant part of this invention as they are a necessary part of my improved method or process of attachin the yarn tubes to the tube carrying ang e. These perforations make possible a very great saving in the time required to assemble a number of yarn tubes and a tube carryingangle int'oa single unit, by simplifying the secure and accurate at-. tachment ofthe tubes onto the angle. With my improved angle, to makesuch an attach ment it is only necessary to place the re uisite number of yarn tubes A, m a suitable I As the application of the flux and the solder ma be made by floating them through theper orations 6 it requires muc less time and heat to produce a secure and satisfactory union between the parts, and so reduces to-a very appreciable extent the cost of producing such units. It also assures a more'uniform product, both inform and strength.

What I claim as my invention and desire tosecure by Letters Patent is:

1. A yarn tube unit com rising a metal angle havi? a bead forme along the free ange thereof by making a double bend therein said" bead project-in the face of said flange; a series 0 perfora tions through said flange and a plurality of metal yarn tubes the upper part thereof solggrgd to the face Of'Sflld flan e below said beyond 2. A yarn tube unit comprising a metal angle having a series of perforations through one flange thereof, and a plurality of yarn tubes the upper part thereof soldered to the face of the perforated flange of said angle.

3. A yarn tube unit comprising a metal angle having a bead formed along the free edge of one flange thereof said bead projecting beyond the face of said flange; a series of perforations throu h said flange and below said bead; and a p urality of yarn tubes soldered to the face of said flange below said bead.

4. In a yarn tube carrying angle, a strip of comparatively thin sheet metal shaped into an angle, one flange of said angle having a msaom series of spaced perforations formed therein through one flange of sai angle, placing the yarn tubes under said perforations and substantially in contact with said flange, applying a suitable flux, and flowingnielted solder into and through said perforations.

' In testimony whereof I have afiixed my signature.

CHARLES H. COLLINS.
